# jwt-go
[![Build Status](https://travis-ci.org/dgrijalva/jwt-go.svg?branch=master)](https://travis-ci.org/dgrijalva/jwt-go)
[![build](https://github.com/golang-jwt/jwt/actions/workflows/build.yml/badge.svg)](https://github.com/golang-jwt/jwt/actions/workflows/build.yml)
[![Go Reference](https://pkg.go.dev/badge/github.com/golang-jwt/jwt.svg)](https://pkg.go.dev/github.com/golang-jwt/jwt)
**BREAKING CHANGES:*** Version 3.0.0 is here. It includes _a lot_ of changes including a few that break the API. We've tried to break as few things as possible, so there should just be a few type signature changes. A full list of breaking changes is available in `VERSION_HISTORY.md`. See `MIGRATION_GUIDE.md` for more information on updating your code.
A [go](http://www.golang.org) (or 'golang' for search engine friendliness) implementation of [JSON Web Tokens](https://datatracker.ietf.org/doc/html/rfc7519).
**NOTICE:** A vulnerability in JWT was [recently published](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/). As this library doesn't force users to validate the `alg` is what they expected, it's possible your usage is effected. There will be an update soon to remedy this, and it will likey require backwards-incompatible changes to the API. In the short term, please make sure your implementation verifies the `alg` is what you expect.
**IMPORT PATH CHANGE:** Starting from [v3.2.1](https://github.com/golang-jwt/jwt/releases/tag/v3.2.1), the import path has changed from `github.com/dgrijalva/jwt-go` to `github.com/golang-jwt/jwt`. After the original author of the library suggested migrating the maintenance of `jwt-go`, a dedicated team of open source maintainers decided to clone the existing library into this repository. See [dgrijalva/jwt-go#462](https://github.com/dgrijalva/jwt-go/issues/462) for a detailed discussion on this topic.
Future releases will be using the `github.com/golang-jwt/jwt` import path and continue the existing versioning scheme of `v3.x.x+incompatible`. Backwards-compatible patches and fixes will be done on the `v3` release branch, where as new build-breaking features will be developed in a `v4` release, possibly including a SIV-style import path.
**SECURITY NOTICE:** Some older versions of Go have a security issue in the crypto/elliptic. Recommendation is to upgrade to at least 1.15 See issue [dgrijalva/jwt-go#216](https://github.com/dgrijalva/jwt-go/issues/216) for more detail.
**SECURITY NOTICE:** It's important that you [validate the `alg` presented is what you expect](https://auth0.com/blog/critical-vulnerabilities-in-json-web-token-libraries/). This library attempts to make it easy to do the right thing by requiring key types match the expected alg, but you should take the extra step to verify it in your usage. See the examples provided.
### Supported Go versions
Our support of Go versions is aligned with Go's [version release policy](https://golang.org/doc/devel/release#policy).
So we will support a major version of Go until there are two newer major releases.
We no longer support building jwt-go with unsupported Go versions, as these contain security vulnerabilities
which will not be fixed.
## What the heck is a JWT?
JWT.io has [a great introduction](https://jwt.io/introduction) to JSON Web Tokens.
In short, it's a signed JSON object that does something useful (for example, authentication). It's commonly used for `Bearer` tokens in Oauth 2. A token is made of three parts, separated by `.`'s. The first two parts are JSON objects, that have been [base64url](http://tools.ietf.org/html/rfc4648) encoded. The last part is the signature, encoded the same way.

The first two parts are JSON objects, that have been [base64url](https://datatracker.ietf.org/doc/html/rfc4648) encoded. The last part is the signature, encoded the same way.
The first part is called the header. It contains the necessary information for verifying the last part, the signature. For example, which encryption method was used for signing and what key was used.
The part in the middle is the interesting bit. It's called the Claims and contains the actual stuff you care about. Refer to [the RFC](http://self-issued.info/docs/draft-jones-json-web-token.html) for information about reserved keys and the proper way to add your own.

This library publishes all the necessary components for adding your own signing methods. Simply implement the `SigningMethod` interface and register a factory method using `RegisterSigningMethod`.

## Project Status & Versioning
This library is considered production ready. Feedback and feature requests are appreciated. The API should be considered stable. There should be very few backwards-incompatible changes outside of major version updates (and only with good reason).
This project uses [Semantic Versioning 2.0.0](http://semver.org). Accepted pull requests will land on `master`. Periodically, versions will be tagged from `master`. You can find all the releases on [the project releases page](https://github.com/dgrijalva/jwt-go/releases).

While we try to make it obvious when we make breaking changes, there isn't a great mechanism for pushing announcements out to users. You may want to use this alternative package include: `gopkg.in/dgrijalva/jwt-go.v2`. It will do the right thing WRT semantic versioning.

## Usage Tips
@ -68,6 +84,14 @@ Symmetric signing methods, such as HSA, use only a single secret. This is probab
Asymmetric signing methods, such as RSA, use different keys for signing and verifying tokens. This makes it possible to produce tokens with a private key, and allow any consumer to access the public key for verification.
### Signing Methods and Key Types
Each signing method expects a different object type for its signing keys. See the package documentation for details. Here are the most common ones:
* The [HMAC signing method](https://pkg.go.dev/github.com/golang-jwt/jwt#SigningMethodHMAC) (`HS256`,`HS384`,`HS512`) expect `[]byte` values for signing and validation
* The [RSA signing method](https://pkg.go.dev/github.com/golang-jwt/jwt#SigningMethodRSA) (`RS256`,`RS384`,`RS512`) expect `*rsa.PrivateKey` for signing and `*rsa.PublicKey` for validation
* The [ECDSA signing method](https://pkg.go.dev/github.com/golang-jwt/jwt#SigningMethodECDSA) (`ES256`,`ES384`,`ES512`) expect `*ecdsa.PrivateKey` for signing and `*ecdsa.PublicKey` for validation
### JWT and OAuth
It's worth mentioning that OAuth and JWT are not the same thing. A JWT token is simply a signed JSON object. It can be used anywhere such a thing is useful. There is some confusion, though, as JWT is the most common type of bearer token used in OAuth2 authentication.
@ -78,8 +102,12 @@ Without going too far down the rabbit hole, here's a description of the interact
* OAuth defines several options for passing around authentication data. One popular method is called a "bearer token". A bearer token is simply a string that _should_ only be held by an authenticated user. Thus, simply presenting this token proves your identity. You can probably derive from here why a JWT might make a good bearer token.
* Because bearer tokens are used for authentication, it's important they're kept secret. This is why transactions that use bearer tokens typically happen over SSL.
### Troubleshooting
This library uses descriptive error messages whenever possible. If you are not getting the expected result, have a look at the errors. The most common place people get stuck is providing the correct type of key to the parser. See the above section on signing methods and key types.
